Who has the right of way at a four-way stop?

Answer: B — The first vehicle to arrive at the stop sign

The correct choice is that the first vehicle to arrive at the stop sign has the right of way at a four-way stop. This rule is grounded in the principles of traffic management and safety, enabling an orderly flow of vehicles at intersections. When multiple vehicles approach a four-way stop simultaneously, the vehicle that comes to a complete stop first is entitled to proceed first. This helps prevent confusion and potential accidents, as drivers can predict the movements of others based on their arrival times. The idea of giving priority to the first vehicle encourages drivers to be attentive and reduces the likelihood of hesitation or second-guessing at the intersection, which can be a common cause of collisions. Understanding and complying with this rule is essential for safe driving and effective navigation through four-way stops.
